Honda 14510-5A2-A02 Genuine Timing Chain Tensioner — for K24 Engines (2.4L DOHC i-VTEC)

A rattling noise from the front of the engine on cold start, chain slap that gets worse with RPM, or a check engine light for timing chain-related codes — these are common signs that your timing chain tensioner is failing. A worn tensioner can allow the chain to jump teeth, leading to severe engine damage or a complete timing failure. Replacing it with this genuine Honda part restores proper chain tension and protects your engine.

This is a factory-original Honda timing chain tensioner (OE part number 14510-5A2-A02) for K24 series engines. It is engineered with the correct hydraulic dampening, piston travel, and spring rate to maintain chain tension across all RPM ranges, from idle to redline. This is the same part sold at Honda dealerships.

•    Visible oil leak from the tensioner gasket or seal
•    Excessive chain slack felt during manual rotation (if engine is accessible)
•    Do not attempt to repair or reset the old tensioner — always replace with a new genuine unit

Condition
New (100% genuine Honda packaging)

Product Type
Timing Chain Tensioner (hydraulic, ratcheting type)

Function
Maintains correct tension on the timing chain, ensuring proper camshaft-to-crankshaft synchronization. The hydraulic piston uses engine oil pressure to apply force to the chain tensioner arm, while the ratchet mechanism locks the piston to prevent chain loosening when the engine stops.

Applications
This tensioner fits K24 series 2.4L DOHC i-VTEC engines found in numerous Honda and Acura models from approximately 2012 through 2020. It is not compatible with K20, J-series, or R-series engines.

Important: Always use the VIN (Vehicle Identification Number) to confirm compatibility with your specific vehicle. If in doubt, send us your VIN before ordering and we’ll verify for you.

FAQ

Is this a genuine Honda part or a copy?
This is 100% genuine Honda OEM — in original factory packaging with Honda part number and holographic seal. It is not an aftermarket brand or a replica.

Does this fit my 2015 Honda CR-V?
If your CR-V has the 2.4L K24 engine, yes. We recommend verifying with your VIN, as some 2015 CR-Vs (especially early production) may have a different tensioner revision.

What’s the difference between 14510-5A2-A01 and 14510-5A2-A02?
A02 is the superseded part number — it replaces A01. A02 includes updated internal materials and revised piston spring rate to improve long-term durability. It is fully backward-compatible.

Do I need to replace the timing chain at the same time?
Not required, but recommended if your chain is stretched or the engine has high mileage (over 120,000 km / 75,000 miles). The tensioner alone is often replaced as a maintenance item.

Will this come with the mounting bolt?
Most genuine Honda packages include the gasket/seal. The main mounting bolt is often reused — check your original. If you require a new bolt, order it separately (Honda part number 14511-5A2-A00, if applicable).

How do I know if my tensioner has failed?
Listen for a ticking/rattle noise on cold start, and check for timing-related diagnostic trouble codes. If the tensioner has collapsed, you may also notice low oil pressure at the front of the engine.
